JANUS moves Windows known folders to a separate drive safely
Move Windows known folders such as Desktop, Documents and Downloads to a secondary drive after a clean install, keeping the system volume dedicated to the OS. JANUS, from momocrackcorp, is a Windows utilities tool that automates folder redirection and verifies file copies before changing system paths. It scans drives, shows used and free capacity, and suits desktop users and administrators who manage multi-drive PCs and frequent reinstalls.
What does JANUS actually do during post-install setup?
JANUS automates migration of the operating system's known folders by copying selected directories to a target drive, calculating folder sizes to estimate needed space, and updating Windows paths only after verifying file integrity. It does not move AppData, which prevents common path-related application errors. The app presents a graphical drive view so you can pick a partition and choose folders individually before any change is applied.
How reliable is the migration and what system impact should I expect?
The tool uses a verify-then-switch workflow, checking copied files before updating system locations, and includes reversible operations with built-in backups. Because it copies data rather than editing files in place, the process primarily uses disk I/O during migration; CPU impact is low. The drive visualization includes used and free capacity so you can confirm target space before starting the copy step.
Is JANUS safe for production machines and does it need technical knowledge?
JANUS prioritizes safety: it never auto-deletes originals and offers restore options, which reduces risk on production systems. The graphical interface guides post-format configuration, so routine use requires only basic desktop skills, while administrators can select folders individually. Advanced users still retain control because the app avoids moving critical profile components and keeps backups until you confirm the redirection.
JANUS is a practical tool for multi-drive setups with one notable trade-off
For administrators and desktop users who perform clean operating system installs on machines with multiple drives, JANUS reduces manual path editing and preserves originals through verified copies and backups. The main trade-off is that it purposely avoids relocating AppData, so any workflows that depend on moving full user profiles remain manual; use JANUS for known-folder migration and keep profile-level changes separate.
